There is several places it can leak back there. In absence of a tester clean the area well and rev the engine to pinpoint the leak. You said it leaks under RPM so that should be easy to find. The EGR cooler can leak if the adapter get porous. The actual EGR valve does not have coolant running through it. Good luck<br /><br />Note the hard line back to the heater core can rot out and leak. Clean it up and i am sure you will find it. Also the lower back portion of the manifold can corrode and leak coolant.
